it is highly highly likely
Nintendo as far as I know does not regularly release their main consoles in like March, and the Super Bowl is in February. Look at the announcement trailer for the Switch- it has that mega contemporary like smart advertising vibe. Definitely the same vein of a Super Bowl commercial
I would bet almost anything that they will have an advert during the Super Bowl. February is too close to March, and money is not an issue for Nintendo.
if the Switch was coming out next summer or Fall then I wouldn't be so confident- but March? this is a no brainer and not comparable to a lot of Nintendo's system releases in the past because of the proximity to the Super Bowl date-release wise
I also will point out that in the past Nintendo was divided- their handhelds and home consoles released at different times and it was somewhat justified to at times not go insanely heavy on advertising both since that could amount up to a lot. But in new territory situation in which they only have ONE device? they're going to go much harder on advertising than ever before probably
Note: bear in mind the Pokemon Company had a Super Bowl commercial last year. Nintendo will definitely this time around
